Prayer introduction: There is a pagoda built with stone slabs in Yaowang Mountain, and the slate is engraved with the Tripitaka "Ganyur". All the pilgrims who came to Lhasa from afar - poor people holding wooden clothes, wearing dirty leather robes and mumbling words, all found comfort here. This is because Daodeng Dawa, the man who built the stone stupa of the Tripitaka "Kangyur" many years ago, used his personal pilgrimage experience to express his fate with the Buddha without leaving any trace.
